TAPE-APPLYING APPARATUS.

Application led November 26, 1919. Serial No. 340,735.

To all whom t may concern.'

Be it known that I, PERLEY R. GLASS, a citizen of the United States, residing at Wayland, in the county of Middlesex and State of Massachusetts, have invented certain Improvements in Tape-Applying Apparatus, of which the following description,

in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures. v

My invention relatesto apparatus for laying tape upon such surfaces as the uppers of shoes, where it may be used for the rein l5, forcement of the work.

An object of the invention is to provide an improved portable organization which may readily be moved to various parts of the work, and which will eifectivelycause the application and adhesion of thetape there-,-

to. In the accomplishment of this purpose, in

the illustrated embodiment of the ap aratus,

a frame, arranged to be grapsed by t e operator to advance it over the surface upon 35 which the tape is laid, carries a ressure surface with heating means there or and means for supplying tape between the prssure surface and the work.

Another object of the invention is to arrange an improved combination of elements for the division of the tape when the end of the surface to which it is to be applied fis reached. This may be accom lished by ,associating ywith the pressure sur ace on the frame a tape-dividing means, as a cutting member, movable into proximity with the pressure surface. Preferably, this dividing or cutting means is actuated by means arranged for engagement by the hand of the operator grasping the frame.

A further object is to effect, in a better manner, a preliminary feed of the tape in preparation for the feed which occurs during its application. As shown herein, the supplying and applying means are so arranged that the tape is fed to the work during the movement of the apparatus, and there is also co-operating, independently operable tape-feeding means, which may, similarly to the dividing means, be actuated by the hand of the operator which produces the travel of the apparatus. f

Hereinafter other objects will be made Fig. 2 is a horizontal section on the line 2-2 of Fig. 1; and

Fig.` 3 is a perspective view illustrating the use of the apparatus.

The frame 10 1s shown as consisting of a evident, reference. being had to the accomi main or body portion 12 which extends vertically in the operation of the apparatus, u pper and lower arms 14 and 16, respectively, projecting horizontally from the body portion, and a handle 18 connecting the arms and lying generally parallel to the body portion. AAbove the portion 12 at its juncture with-the arm 14 1s an upwardly and rearwardly extending arm 20, at the outer end of which is fixed a horizontal spindle 22 for the support of a roll 24 of the tape which is to be applied. From the roll the tape, which is indicated by the letter T, passes over a guide roll 26 journaled at the juncture of the arms 14 and 20 and the body portion 12, and then enters a vertical passage 28 extending along the body ortion near the side adjacent the handle. merging from the passage, the ta e passes in contact with the inner edge o a yieldable pressure roll 30 mounted upon a leaf spring 32 fastened near its upper end to the outside of the body. Within the passage, the tape, ,which preferably bears, u on its inner side as it is wound upon t .e roll, an adhesive substance adapted to be softened by the applica- Ation of heat is sub'ected to the action of a heating device', pre erably in the form of an electric unit 34 contained within a vertical bore in the body portion parallel to the passage 28. The uncoated side of the tape comes in contact with the heated surface, therefore having no tendency to adhere thereto; while the opposite side, u on which the adhesive materlal is softene is separated from the adjacent wall of the passage by a substantial clearance. To permit the unimpeded travel of the a paratus, the unit is connected to a source oi) current b ilexi- .ble conductors 36, the length of w ich is such as to enable the operatentojmoveitto any part of the support upon which the work is laid. IBelow the roll 30, the tape T crosses a guideway 38, extending horizontally in the arm 16, which arm is of considerable crossfsection and` is recessed to furnish .acasing for the actuating elements of theY apparatus, and then over a curved pressure surface 40, whichrat its lower extreniityv may-be flattened t'o force the tape againstl-the'work over a substantial length.

Mounted to reci rocate in the guideway 38 is a cutting bla e 42 movable across the path of the tape T between the roll 30 and the pressure surface 40. blade, its end adjacent to the handle is connected by a link 44 to an arm 46 fast upon a shaft 48 rotatable between the sides of the arm 16. Fixed to the shaft 48 beside the arm 46 is a segmental pinion l50 meshing with a rack 52 formed upon the lower extremity of a rod 54. This .rod is movable within a vertical bore 56 lying axially of the handle 18 and is guided by openings in the arms 14 and 16.- In a space between the rod and handle and surrounding the formel: is a helical spring 58 contacting with the `arm 16 and with an enlarged portion at the upper end of the rod, so that it exerts its tension to hold the rod in a normally raised position, a stud 60 carried by the arm 14 andv extending into a vertical slot 62 in pressing the ro the roll 7 2 is an arm 74 having pivoted upon .Rotatable about a shaft fixed in the arm 16 is a feed roll 72 co-operating and being horizontally alined with the pressure vroll 30. This roll 72 is preferably corrugated or grooved transversely to cause it to more effectively engage the tape and to give less surface for adhesion. Mounted to os-` cillate about theshaft 70 in proximity to it' a pawl 76 operating-over ratchet teeth 78 surrounding. one extremityA of .the roll 72. This `s 1rnrr-74is joined by a link 80 to, an arm 8 2 fixed-u ons-the shaft 48. The'parts are so related t at asthe shaft 48 is rotated by the downward thrust-of the Vrod 54-during the cutting of the tape T, the pawl 76 moves idly over the ratchet teeth 78. When,

however, the rodvrises under the influence of the spring 58, during which time the blade 42 is being withdrawn, the pawl engages the teeth and rotates lthe roll 72 in an anti-clockwise direction, as viewed in Fig. 1 of the drawings. This produces an To actuate the` advance of the tape, drawing a sulicient amount from the roll 24 to bring its free end beneath the pressure surface 40.

In Fig. 3 my improved apparatus-is =il lustrated as it appears in use when applying tape about a portion of the inner side of a shoe vamp V. The operator, grasping the v'handle 18, presses, by the horizontal portion of the surface 40, \the end of the tape into contact with the beginning of the area to be covered, causing the adhesion of said tape to the work, and then draws the apparatus over the desired area, continuing the downward pressure. This simultaneously p roduces a feed of the tape from the roll 24 and its adhesion to the work, it being first warmed ready for application during its travel through the passage 28, over the pressure roll 30 and beneath the contact surface 40. When the end of the area to be covered is reached, the operator forces down the rod 54 by bearing with his thumb upon the surface 66, or by pressure upon the head 68, producing forward movement of the blade 42 and the severing of the tape. The travel of the apparatus is continued until the end thus made is brought into adhesive contact with the work, and then the apparatus is raised and the rod released. The spring 58, returning the rod to its normal position, causes through the intermediate connections the forward movement of the pawl 76 and the consequent rotation of the roll 72, feeding the end of the tape past the guideway 38 and beneath the pressure surface 40 in preparation for its application to another area. It will be observed that the cutting of the tape and its preliminary feed are accomplished by a single operation through actuating mechanism common to both the blade and the feed roll.
